HYBRID RESET RULES FOR PEAKING AVOIDANCE OF A CLASS OF HIGH-GAIN OBSERVERS
Séance du jeudi 4 avril 2013, 14h. (La salle sera précisée plus tard)
Luca ZACCARIAN, Directeur de Recherche, LAAS-CNRS, Toulouse.
This talk will present two hybrid techniques to augment high-gain observers with suitable reset rules for a class of nonlinear plants with dominant second order dynamics. The proposed hybrid modification enforces an instantaneous jump of the state of the observer if suitable conditions hold. These jump conditions depend on the plant output and on extra states incorporated in the observer which evolve according to some combinations of the output error and of its integral. We show that these hybrid rules succeed at removing peaking and illustrate our result on well known case studies taken from the literature.
